Summary: From 1985 to 1990, the European Commission has realised the CORINE Programme (Coordination of Information on the Environment). That is the Information System on the state of the environment in the European Countries, which should be achieved on the basis of land and vegetation mapping with new technologies, in relatively short time. Experts of the European Commission developed nomenclatures and methodologies for this Programme, unified for all European countries. This mapping started during the ninetieth in Luxemburg, Portugal, Spain and the Netherlands. The company GEOSAT, Zagreb, in cooperation with the Institute for Geodesy, Cartography and Remote Sensing in Budapest, realised the Land Cover Mapping of Istria peninsula in 1995/96, according to CORINE nomenclatures and methodologies. For this mapping different multispectral and multitemporal satellite images have been used (SPOT P and Landsat TM). The SPOT images were transformed into transverse Mercator projection (Bessel ellipsoid). At the same time merging multisensor images were applied by registering the Landsat TM image to the SPOT image. It resulted in new images more convenient for fotointerpretation. The interpretation has been made visually, as well as by computer processing. For the mapping purpose, 44 classes of the CORINE nomenclature (standard level 3) have been selected (mapped). The results of Land Cover Mapping of Istria include: georeferenced satellite image-maps (in Gauss-Krüger projection), scale 1:50 000 and land cover maps at the same scale as well as land cover statistics. This land cover mapping realised in Croatia, according to CORINE Programme, was the first one in former Yugoslavia.
